Hockerton Housing Project was a new-build project but its approach to energy efficiency can be applied to existing homes. In one retrofit of 1950s solid-walled social housing, we delivered an 83.5% reduction in energy use, by super-insulating existing single skin concrete walls. Shares in the community-owned wind turbine in Hockerton provided a cost-effective way to offset carbon emissions we could not cut on-site.
We have been involved in a range of retrofit projects, including the Nottingham Eco Home, but it was the Technology Strategy Board’s Retrofit for the Future competition that allowed us to test those principles in full. The blog below shows our journey from identifying the properties to monitoring energy performance of the retrofit.
